HOLYOKE – Maureen Healy of Holyoke was charged with a two-count felony indictment returned by a grand jury Wednesday in relation to the June death of Thomas P. Monahan, who had come outside to help at a traffic accident involving her car, officials said.

Hampden District Attorney Mark G. Mastroianni announced the indictment in a press release.

Healy, 31, of 91 Lincoln St., at the time of the accident was a Holyoke Police Department records clerk. She was charged with one count of manslaughter by motor vehicle and one count of motor vehicle homicide while under the influence of alcohol and negligent or reckless operation, Mastroianni said.

Healy is set to be arraigned in Hampden Superior Court Sept. 21, he said.

Monahan, 53, of 144 Lincoln St., died June 6 from injuries suffered after a car that had flipped over in front of his home was struck by another car and slammed into him on June 4, police said.

Mary Monahan, of Holyoke, Thomas Monahan’s sister, said the family was satisfied with the investigation but the pain of the loss endures.

Police have said the accident began when a 2003 Honda driven by Healy struck a parked vehicle on Lincoln Street and flipped onto its passenger side on a Saturday about 11:40 p.m.

Monahan suffered injuries that proved to be fatal when, after he and other Lincoln Street neighbors ran outside to help, another car came down Lincoln Street and hit the Honda, which struck Monahan. That car, a 2004 Mitsubishi, was driven by Tiffany Renardson, 22, of 57 Pleasant St., police said.
